Abstract

Example implementations relate to touch-sensitive input devices. As an example, a non-transitory computer readable storage medium comprises instructions that when executed cause a controller of an electronic device to receive, via a touch-sensitive input device of the electronic device, a touch input. The instructions also cause the controller to determine whether the touch input corresponds to a re-orientation input. The instructions further cause the controller to, in response to a determination that the touch input corresponds to the re-orientation input, rotate an input axis associated with the touch sensitive input device from a first orientation to a second orientation based on the re-orientation input.

Description

BACKGROUND
An electronic device may be attached to an input device to receive input from a user of the computing device. For example, an input device may be a keyboard or a computer mouse. Some electronic devices, such as a notebook computer, may have an integrated input device, such as an integrated keyboard.

 DETAILED DESCRIPTION
One type of input device that is becoming more common than keyboard or computer mouse is a touch-sensitive input device. A touch-sensitive input device may translate the movements of a writing tool (e.g., a user's finger or a stylus) to a relative position in a graphical user interface (GUI). An example of a touch-sensitive input device may be a touchpad. Another touch-sensitive input device may be a touchscreen.
A touch-sensitive input device may include an input axis to translate a movement of a writing tool to a relative position in a GUI. However, the input axis may be a fixed input axis designed to face a sole, individual user. When a user is not directly facing the input axis, the touch-sensitive input device may not translate the movements from the user's finger to the correct position in a GUI. Thus, the convenience of using the touch-sensitive input device may be decreased.
Examples described herein provide a touch-sensitive input device that rotates an input axis to align the input axis to a user of the touch-sensitive input device. For example, a non-transitory computer readable storage medium comprising instructions that when executed cause a controller of an electronic device to receive, via a touch-sensitive input device of the electronic device, a touch input. The instructions also cause the controller to determine whether the touch input corresponds to a re-orientation input. The instructions further cause the controller to, in response to a determination that the touch input corresponds to the re-orientation input, rotate an input axis associated with the touch sensitive input device from a first orientation to a second orientation based on the re-orientation input.
As another example, a non-transitory computer-readable storage medium comprising instructions that when executed cause a controller of an electronic device to detect, via a light-sensitive sensor of the electronic device, a direction of a user gesture relative to a side of a touch-sensitive input device of the electronic device. The instructions also cause the controller to rotate an input axis associated with the touch-sensitive input device from a first orientation to a second orientation based on the detected direction, where a vertical axis of the input axis is aligned with the side in the second orientation. Thus, the convenience of using the touch-sensitive input device may be increased.
FIG. 1 illustrates an electronic device 100 with a touch-sensitive input device that rotates an input axis based on a re-orientation input, according to an example. Electronic device 100 may be, for example, a desktop computer, an all-in-one computer, a tablet computing device, a mobile phone, a display, or any other electronic device suitable to receive touch inputs. Electronic device 100 may include a controller 102, a computer-readable storage medium 104, and a touch-sensitive input device 106.
Controller 102 may be a central processing unit (CPU), a semiconductor-based microprocessor, and/or other hardware devices suitable for retrieval and execution of instructions stored in computer-readable storage medium 104. Controller 102 may fetch, decode, and execute instructions 108, 110, and 112 to control a process of rotating an input axis of touch-sensitive input device 106. As an alternative or in addition to retrieving and executing instructions, controller 102 may include at least one electronic circuit that includes electronic components for performing the functionality of instructions 108, 110, 112, or a combination thereof.
Computer-readable storage medium 104 may be any electronic, magnetic, optical, or other physical storage device that contains or stores executable instructions. Thus, computer-readable storage medium 104 may be, for example, Random Access Memory (RAM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a storage device, an optical disc, etc. In some examples, computer-readable storage medium 104 may be a non-transitory storage medium, where the term “non-transitory” does not encompass transitory propagating signals. As described in detail below, computer-readable storage medium 104 may be encoded with a series of processor executable instructions 108-112.
Touch-sensitive input device 106 may be a touchpad, a touchscreen, or any other electronic device suitable to translate the movements of a writing tool (e.g., a user's finger or a stylus) to a relative position in a GUI based on an input axis. An example of an input axis is described in more detail in FIGS. 2A-2B.
Touch input reception instructions 108 may receive a touch input 114 via touch-sensitive input device 106. Re-orientation input determination instructions 110 may determine whether touch input 114 corresponds to a re-orientation input. A re-orientation input may have a distinct characteristic. For example, a re-orientation input may correspond to a tapping gesture on touch-sensitive input device 106. As another example, a re-orientation input may correspond to a two finger swipe from one side of touch-sensitive input device 106 to another side of touch-sensitive input device 106.
When re-orientation input determination instructions 110 detect the distinct characteristic, re-orientation input determination instructions 110 may determine that a re-orientation input has been received. In response to a determination that touch input 114 corresponds to a re-orientation input, input axis rotation instructions 112 may rotate the input axis of touch-sensitive input device 106 from a first orientation to a second orientation based on the re-orientation input. For example, input axis rotation instructions 112 may identify a location of the re-orientation input in touch-sensitive input device 106. Input axis rotation instructions 112 may determine an anchor point based on the location and rotate the input axis based on the anchor point from a first orientation to a second orientation. A vertical axis of the input axis may be aligned with the anchor point in the second orientation.
FIGS. 2A-2B illustrate a process of touch-sensitive input device 106 rotating an input axis based on a re-orientation input, according to an example. In FIG. 2A, touch-sensitive input device 106 may include an input axis 202. Input axis 202 may be virtual and may be implemented using instructions executable by a controller, such as controller 102 of FIG. 1. In some examples, input axis 202 may not be visible to a user of touch-sensitive input device 106. Input axis 202 may be a two dimensional axis. Input axis 202 may include a horizontal axis 204 and a vertical axis 206.
Input axis 202 may determine how movements detected on touch-sensitive input device 106 is translated to a relative position in a GUI 208. GUI 208 may be shown in a display attached to electronic device 100. For example, input axis 202 may be in a first orientation as shown in FIG. 2A. In the first orientation, input axis 202 may be aligned with a first user 210. When a first user 210 of touch-sensitive input device 106 moves a finger across touch-sensitive input device 106 (as shown by an arrow 212), a pointer 214 may move across GUI 208 from a first position to a second position (as shown by an arrow 216).
When a second user 218 is to use touch-sensitive input device 106, second user 218 may re-orient input axis 202 to better suit second user's 218 position relative to touch-sensitive input device 106. As shown in FIG. 2A, second user 218 may physically face a corner of touch-sensitive input device 106 and may not be aligned with input axis 202 in the first orientation. Second user 218 may provide a re-orientation input 220 to touch-sensitive input device 106 to re-align input axis 202 with second user 218.
Touch-sensitive input device 106 may identify that re-orientation input 220 is received at a location 222 in touch-sensitive input device 106. Location 222 may correspond to a region of touch-sensitive input device 106 where re-orientation input 220 initially makes physical contact with touch-sensitive input device 106. Touch-sensitive input device 106 may determine an anchor point 224 based on location 222. Anchor point 224 may be a location in touch-sensitive input device 106 that serves as a reference point to re-orient input axis 202. For example, anchor point 224 may be a center of location 222.
Turning to FIG. 2B, touch-sensitive input device 106 may rotate input axis 202 to a second orientation based on anchor point 224 while touch-sensitive input device 106 and electronic device 100 are to remain stationary. In the second orientation, vertical axis 206 of input axis 202 may align with anchor point 224 such that a proximal side 226 of vertical axis 206 is to intersect anchor point 224. Proximal side 226 may be a side of vertical axis 206 that is below horizontal axis 204. In the second orientation, input axis 202 is aligned with second user 218. Thus, second user 218 may navigate GUI 208 without having to physically re-orient touch-sensitive input device 106. For example, to move pointer 214 from the second position to a third position (as shown by arrow 228), second user 218 may move a finger across touch-sensitive input device 106 (as shown by an arrow 230).
FIG. 3 illustrates an electronic device 300 with a touch-sensitive input device that rotates an input axis based on a triggering of a sensor, according to an example. Electronic device 300 may be similar to electronic device 100 of FIG. 1. Electronic device 300 may include controller 102, touch-sensitive input device 106, a computer-readable storage medium 302, and a set of sensors 304. Computer-readable storage medium 302 may be similar to computer-readable storage medium 104. A set of sensors 304 may include a plurality of sensors. Examples of set of sensors 304 are described in more detail in FIGS. 4 and 6. Set of sensors 304 may be light-sensitive sensors that surround touch-sensitive input device 106. Computer-readable storage medium 302 may be encoded with a series of processor executable instructions 306-308.
User gesture direction detection instructions 306 may detect a direction of a user gesture relative to touch-sensitive input device 106 based on a triggering of a sensor in set of sensors 304. Input axis rotation instructions 308 may determine an anchor point based on the detected direction. Input axis rotation instructions 308 may also rotate an input axis of touch-sensitive input device 106 based on the anchor point.
FIG. 4 illustrates an electronic device 400 with a touch-sensitive input device that rotates an input axis based on a triggering of a sensor, according to another example. Electronic device 400 may implement electronic device 300 of FIG. 3. Electronic device 400 may include controller 102, a touch-sensitive input device 402, and a plurality of sensors 404-410 that surrounds touch-sensitive input device 402. Touch-sensitive input device 402 may be similar to touch-sensitive input device 106. Each of sensors 404-410 may be a light-sensitive sensor that is triggered (e.g., generates a voltage) in response to a change in light intensity detected at the light-sensitive sensor. For example, each of sensors 404-410 may be implemented using a photo transistor that detects shadow.
Touch-sensitive input device 402 may have a square sharp or a rectangular shape. Touch-sensitive input device 402 may have a first side 412, a second side 414, a third side 416, and a fourth side 418. Each of sides 412-418 may be aligned with a distinct sensor from the plurality of sensors 404-410. For example, a first sensor 404 is aligned with first side 412, a second sensor 406 is aligned with second side 414, a third sensor 408 is aligned with third side 416, and a fourth sensor 410 is aligned with fourth side 418.
During operation, sensors 404-410 may detect a direction of a user gesture relative to touch-sensitive input device 402 so that touch-sensitive input device 402 may rotate to align with the direction of the user gesture, as described in more detail in FIGS. 5A-5D.
FIGS. 5A-5B illustrate a process of touch-sensitive input device 402 rotating an input axis based on a triggering of a sensor, according to an example. Turning to FIG. 5A, touch-sensitive input device 402 may include input axis 202. Input axis 202 may be in a first orientation. To re-orient input axis 202, a user 502 of touch-sensitive input device 402 facing second side 414 of touch-sensitive input device 402 may reach a hand or a finger towards touch-sensitive input device 402. When the hand or finger hover over second sensor 406, second sensor 406 may detect a shadow caused by the hand or finger. In response to detecting the shadow, second sensor 406 may be triggered. The triggering of second sensor 406 may indicate that the direction of the hand or finger is coming from second side 414. Based on the detected direction, touch-sensitive input device 402 may rotate input axis 202, as described in more detail in FIG. 5B.
Touch-sensitive input device 402 may determine an anchor point 504 based on the detected direction. For example, since second sensor 406 is triggered, touch-sensitive input device 402 may determine that the direction of user's 502 hand or finger is coming from second side 414. In some examples, anchor point 504 may be located at a mid-point of second side 414. In some examples, anchor point 504 may be located anywhere in a region of touch-sensitive input device 402 that is aligned with second sensor 406. Touch-sensitive input device 402 may rotate input axis 202 from the first orientation to a second orientation to align vertical axis 206 with anchor point 504. In the second orientation, proximal side 226 may intersect with anchor point 504.
Turning to FIG. 5C, another example of touch-sensitive input device 402 rotating input axis 202 based on a triggering of a sensor is described. In FIG. 5C, user 502 may face fourth side 418 of touch-sensitive input device 402. In response to detecting breaking light caused by a hand or finger of user 502, fourth sensor 410 may be triggered. In response to the triggering of fourth sensor 410, touch-sensitive input device 402 may determine that the direction of user's 502 hand or finger is coming from fourth side 418. Thus, touch-sensitive input device 402 may determine an anchor point 506 based on the detected direction. Touch-sensitive input device 402 may rotate input axis 202 from the first orientation to a third orientation to align vertical axis 206 with anchor point 506. In the third orientation, proximal side 226 may intersect with anchor point 506.
Turning to FIG. 5D, another example of touch-sensitive input device 402 rotating input axis 202 based on a triggering of a sensor is described. Electronic device 400 may further include a set of indicators 508, 510, 512, and 514. Each of indicators 508-514 may be aligned with a corresponding side of touch-sensitive input device 402. For example, a first indicator 508 may be aligned with first side 412, a second indicator 510 may be aligned with second side 414, a third indicator 512 may be aligned with third side 416, and a fourth indicator 514 may be aligned with fourth side 418.
Indicators 508-514 may be implemented using light emitting diodes. Indicators 508-514 may provide a visual indication of which side of touch-sensitive input device 402 proximal side 226 is aligned with. Thus, a user of touch-sensitive input device 402 may determine the current orientation of touch-sensitive input device 402 using indicators 508-514. For example, proximal side 226 may be aligned with third side 416 initially. Third indicator 512 may light up. Input axis 202 may be rotated as described in FIGS. 5A-5C and proximal side 226 may be aligned with fourth side 418 after the rotation. Thus, third indicator 512 may turn dark and fourth indicator 514 may light up.
FIG. 6 illustrates a touch-sensitive input device 600 that rotates an input axis based on a triggering of a sensor, according to another example. Touch-sensitive input device 600 may have a circular shape. A band of sensors 602 may surround touch-sensitive input device 600. Band of sensors 602 may include a plurality of sensors, such as sensors 604, 606, and 608. Band of sensors may be light-sensitive sensors. Operations of touch-sensitive input device 600 and band of sensors 602 may be similar to touch-sensitive input device 402 and set of sensors 404-410 of FIG. 4. However, compared to set of sensors 404-410, band of sensors 602 may include more sensors. Thus, direction of gesture from a user may be more precisely detected and an anchor point to align an input axis of touch-sensitive input device 600 may be more precisely placed in touch-sensitive input device 600.
In some examples, when contiguous sensors of band of sensors 602 detect a shadow, touch-sensitive input device 600 may determine an anchor in different manners based on the number of the contiguous sensors. When an odd number of contiguous sensors of band of sensors 602 detect a shadow, the middle sensor among the contiguous sensors may define an anchor point. When an even number of contiguous sensors detect a shadow, a halfway point between the middle two sensors may define the anchor point.
